Honda Super Cub C100 1964 restoration

[iserbil]

My Honda Super cub c100
The history:
my uncel lived in a coast town in south norway, and somehow he got his hands on this bike when he was young, he didnt know how rare it was and wanted to scrap it whne he got older.. then i refused and took it , and now im trying to get it to start/splitting the motor to change the seals and potentialy other stuff..

so, here is my beauty! ( when i started)


pretty smal when its parked beside the Ural

then i took out the engine


and yesterday i got my flywheel puller, but i used a screwdriver to lock the engine while taking the flywheel off? do you think this caused anny damage to the engine/piston? :?



and iv orderd new gaskets...

cause its leaking pretty much, thats the reason it was put away many years ago...
my main priority is to get the engine working before i start with the bike itself...
got any tips whne dissambeling the engine? any parts that i should change/ any parts that usaly brakes after 50 years
? , id would be nice to know

[MRB3N]

50 years Iserbil? Haha! Erm everything?

Nah, its a Honda, so probably some new gaskets, spark plug and some fresh fuel and it will fire up.

[iserbil]

iv bought a new plug, new battery, and just got the new gaskets today think i'm going to start dissasemebeling the engine tomorow stay tuned!

[iserbil]

just found out that i need a new piston and piston rings anywas




the guy who have taken the engine apart befroe me aparently forgot to put in new gaskets so, the piston is at the point og getting ruined cause of lack of luberication, byt the sylinder seems to be fine
the vales need a clean


and im shure im gonna remember to replace the gaskets haha

[iserbil]

just orderd a new Piston ( orginal size) , and some piston rings, not gonna bore it but im gonne polish it inside, i dont know what it is called in english...
tomorow im hoping to get the valves out and get them polished and maybe clean the airfilter?

Will feel like a brand new bike even though its 50 years old!

And yes dont forget the gaskets! Haha!

Maybe replace the air filter? If not then just clean it with fuel.

yeah, im going to clean the air filter, and the carb and get some frash fuel and maybe install a fuel filter....
but...
cleaned the top and the valves today...
got the valves off after along struggle and lots of improvising...
the valve puller was to big.. :lol: so i had to find a new way to take them off using a hammer and a screwdriver ( i dint hammer on them... i did just push with the things on the back of the hammer )

and then its ready to get cleaned...

looks like someone rode off with the choke on


tested out cleaning them using a drill..

testing out if its quality cleaning grease haha

then i did put some claening thing on the valves and started turning them arround...


scraped a bit more on the top after this pic was taken...

but here is the valves finished


now they open close like they should

[MRB3N]

Nice one! Much much better.

You look like you've got a pretty decent workshop there too!

I wish I had a space like that to mess about in. Id never leave!

[iserbil]

hehe , tahts jsut the part cave not realy the garage..
nothing more to do on the engine before i get my pison and rings... so i started making a custom exhaust today..
this was the plan..

not that many taht drive arround with 3" pipes on their 50cc



after some welding (actualy my first weld ever^^)

and..

hoping to test fit is soon

[iserbil]

im not a master welder haha

big driffrence between orginal and 3" ^^

now im only missing the brackets... im gonna make those after im done with the engine... cause i have to test fit it..


so, what coulor should i paint it in ? black?

[MRB3N]

I reckon you should paint the downpipe black but then could you shine the 3 inch pipe up?

If you can then do that. Would look really nice with a shiny, fat pipe sticking out.

Also whats the laws there about exhausts? Is that going to be legal?

i dont realy care about beeing legal,,, cause we dont have MOT on motorbikes in norway

[iserbil]

just got some stickers... some vintage and some new... no new ones is going on the cub

some random stickers on my exhaust, i cant have anything there cause of the heat tho :?
and here is my piston rings, looks old the case is old and wierd and got lots of black spots , looks like oil

the piston rings looks good tho, anybody knows how i know whats up and down on thees thing and which is on the top/middle/bottom?
i need some help here..

[MRB3N]

Not sure if theres an up or down. If theres writing on the ring, put that to the top.

As for which is top middle or bottom I really not sure.

Im sure 5 mins on Google will tell you though.

Ill have a look if I get some time for you mate.

[iserbil]
